DSGSVDSetDimensions#

Sets the number of columns and rows for a DSGSVD.

Synopsis#

#include "slepcds.h" 
PetscErrorCode DSGSVDSetDimensions(DS ds,PetscInt m,PetscInt p)

Logically Collective

Input Parameters#

  • ds - the direct solver context

  • m - the number of columns

  • p - the number of rows for the second matrix (B)

Notes#

This call is complementary to DSSetDimensions(), to provide two dimensions that are specific to this DS type. The number of rows for the first matrix (A) is set by DSSetDimensions().

Use PETSC_CURRENT to leave any of the values unchanged. Use PETSC_DETERMINE to set m to the leading dimension and p to the number of columns of B.
